Overview

The new VA550 flow sensor operates based on the principle of calorimeter measurement. Therefore, no additional temperature and pressure compensation is required. Due to its robust design, aluminum die cast casing, and sturdy sensor made of stainless steel 14571, the new VA550 flow sensor is suitable for harsh industrial applications and harsh environments. The ATEX version is suitable for applications in explosive areas. For flow measurement of natural gas, there are versions with DVWG inlet. Unlike the previously used bridge circuit, the newly developed evaluation electronic device records all measurement values digitally. This allows for very * * and fast measurements over a wide temperature range of up to 180 ° C (separated by 350 ° C). The measurement range is 1 ... 1000, VA550 has integrated Modbus output as standard, and all parameters such as Nm3/h, Nm3, Nm/s, Nl/min, Nl/s, kg/h, kg/min, ft/min, ° C, etc. can be transferred. All parameters can be adjusted directly on the instrument (through the display screen) or through handheld PI500 and current isolated pulse output for total consumption. Can be done through Modbus

VA 550 flow and consumption meter

The new flow sensor VA550 operates based on the principle of calorimeter measurement.Therefore, no additional temperature and pressure compensation is required.Due to its robust design, aluminum die cast casing, and sturdy sensor made of stainless steel 14571, the new VA 550 is suitable for harsh industrial applications and harsh environments.The ATEX version is suitable for applications in explosive areas.For flow measurement of natural gas, there are versions with DVWG inlet.

Unlike the previously used bridge circuit, the newly developed evaluation electronic device records all measurement values digitally.This allows for very * * and fast measurements over a wide temperature range of up to 180 ° C (separated by 350 ° C).The measurement range is 1 1000, VA 550 has integrated Modbus output as standard, and all parameters such as Nm3/h, Nm3, Nm/s, Nl/min, Nl/s, kg/h, kg/min, ft/min, ° C, etc. can be transferred.All parameters can be adjusted directly on the instrument (through the display screen) or through handheld PI 500 and current isolated pulse output for total consumption.

Remote diagnosis can be performed through Modbus, and if necessary, all relevant parameters can be checked and changed.Therefore, it is possible to change the process conditions.Through remote diagnosis and status updates, such as temperature exceeding, sensor faults or calibration dates can be determined.
